Because of the increase in the numbers of vehicles and drivers, traffic congestion causes anger on the road to occur frequently. In addition to the impact of personality traits, the information processing of emotional stimuli also influences drivers' behaviours. Research is needed to understand how drivers interact with anger stimuli and the differences in processing anger information between safe and dangerous drivers. This study aimed to explore the differences between safe and dangerous drivers' negativity bias towards anger and discuss the causes of dangerous driving behaviours from the perspective of information processing. In total, 34 participants were divided into a safe group and dangerous group based on their traffic violation history and driving behaviour trends. Participants completed an emotional Stroop task with event-related potential (ERP) data. The results showed that the P200 amplitudes of dangerous drivers were significantly reduced compared with those of safe drivers when processing angry and neutral faces, indicating the inadequate assessment of angry faces in early emotional processing. The N170 amplitudes of dangerous drivers were significantly reduced compared with those of safe drivers when processing angry faces, demonstrating decreased negative input that is potentially related to dispositional fearlessness and uncaring traits. This study revealed negativity bias towards anger in dangerous drivers based on ERP evidence, enabling us to understand the differences in driving behaviours from the perspective of physiological mechanisms.
由于车辆和驾驶员数量的增加，交通拥堵导致道路上的愤怒情绪频繁发生。除了人格特质的影响外，情绪刺激的信息处理也会影响驾驶员的行为。需要研究来了解驾驶员如何与愤怒刺激相互作用，以及安全和危险驾驶员在处理愤怒信息方面的差异。本研究旨在探讨安全和危险驾驶员对愤怒的负性偏向差异，并从信息处理的角度探讨危险驾驶行为的原因。共有 34 名参与者根据他们的交通违规历史和驾驶行为趋势分为安全组和危险组。参与者完成了带有事件相关电位（ERP）数据的情绪 Stroop 任务。结果表明，在处理愤怒和中性面孔时，危险驾驶员的 P200 振幅明显低于安全驾驶员，表明在早期情绪处理中对愤怒面孔的评估不足。在处理愤怒面孔时，危险驾驶员的 N170 振幅明显低于安全驾驶员，表明负面输入减少，这可能与性格上的无畏和漠不关心有关。这项研究基于 ERP 证据揭示了危险驾驶员对愤怒的负性偏向，使我们能够从生理机制的角度理解驾驶行为的差异。
